Anything Direct Drive related (SERIOUS)

For 2WD, I wouldn’t want to offer it or recommend it.

@torqueboards You are saying that it wasn’t enjoyable, not enough torque even on 75KV… but I am talking about the 60KV, they should have better torque than the 75KV.

Haven’t tried 60KV yet TBH. Might be better but I honestly wouldn’t recommend it unless 4WD.

You can try it and I have the adapters. Just PM me.

By trying them, you mean buying them and report back :smiley: I am not Croesus, this is why I would like @DerelictRobot to report back on his thoughts :slight_smile:

Changing the Kv won’t help if your ESC isn’t overheating, and if your motor is overheatign changing the Kv won’t help also

If the motors are cool and your ESC can handle just increase increase the current, increasing the motor current by 1.5 times will have the same result as going to the 60 Kv on the same current as now

He’s tested it on 4WD if I’m not mistaken. @Ahrav ran it on 4WD too.

I am already at 75A per motor, 70A for the battery (I can push to 80A for the battery, but the 50E aren’t made to pull more than that)

For science, and my wallet, I would like @DerelictRobot to try on 2WD 60KV if he has time :smiley:
@ahrav is on 4WD 90KV with AT wheels, and he says he has plenty of torque, might be the way to go

Just increase the motor current, leave the battery as is, you will have more torque, but will tapper down early

Just make sure you have the motor temperature sensors working so you don’t cook them accidentally

Unless mistaken, the DD are rated for 80A max, @torqueboards correct ?

He’s offline now but here’s some user information about the TBDD and talking about outrunner 6380’s:

Yeah but it depends on the Kv

A higher Kv motor can take more current for the same heat loss

Motors are rated for torque, the different Kv options only change at what current and speed that torque can be produced

For example, if you went with the 60 Kv motor and kept the same current settings you have now, it would increase the torque, but your motor woudl heat more, depending on where you ride, way more

If you are looking to gauge torque sorts objectively use this guy https://calc.3dservisas.eu/

It’ll
Give you torque values based on your setup. Granted there are other factors in play.

Nonetheless it’s a good baseline. You can also toggle between 4wd and 2WD and you’ll see the big difference it has.

EDIT: I’ve gone awd with 90kV and AT. I had zero issues whatsoever. Motors got hottter a bit faster than thane which I expected but the torque was still better than a 2WD with thane… again personal experience but doable. I would recommend 4wd with DDs until tested with 2WD at a low kV.

I’m just thinking about going down the TB 75kV direct drive path to build an Evo downhill powers slide beast.

Component failure could be catastrophic. Should I consider belts??

I have a set of mk2 elofty direct drives that I recently rebuilt. These are the 60kv even with 150mm airless I can go up hills. I have also have a set of eovan direct drive with the pinwheel adaptors and the 150mm pneumatics with pinwheel fitting. the torque is hopeless. The only thing I can do with this setup is buy another eovan direct drive with pinwheels and go 4x4. Eovan warned me when I ordered it wasn’t recommended and the pinwheels adaptors for their DD was more for their 105mm bacon strips.

Hi Everybody,

I am interested in a lightest possible approx. 250W direct drive to be used as a controlled brake unit.

I came across these skateboard motors and I do not understand their (1500W - 2000W) output.

Can you please tell what is these motors’ sustainable /continuous power ?

If you can recommend to me on any good such small and light motors, that will be appreciated!
(can the motor housing be made of carbon fiber?)

Thanks!!

Hi guys,

I’ve got a 3wd 58kV elofty DD (first ever batch) board which used to be 4wd, running on Trampa UrbanThreads 6.5" tyres. The motor in question lasted for about 5 miles (I haven’t ridden the board since obviously)

In the likely event that I won’t be able to fix it, and given that I enjoyed every single second riding the board when it was running will all four motors, I’d like to replace this with more of the same, but better.

Which DD should I go for?

Pic for attention.

Hello
All DDs have problems
A few months ago I would have advised to go the Torque Board road but it looks like there’s more and more problems with them :roll_eyes:
You have the ‘Elofty’ third’Gen but I also read some have problems
Not helping at all, sorry
My Gen 2 seems to hold but I’m lightweight and I don’t ride a lot.

BTW what’s happening with your drive? You hear a sound, it’s locked…?

Not locked yet but there’s a “step” in the rotation that sounds rough af. I’m disassembling the rest of the unit today and I’ll see what else I can find

Well if that’s not one of the bearings then either magnet bits are crunching in the gap or stator wires grinding what else is left
